plot(x,multiplier=1,...)vectors representing points in d-dimensional space
direction of the mode for a cone/normal bump
angle between peak of the cone and the base of the cone
(d x d) positive definite shape matrix
matrix used to compute || A x ||_p
power of the l^p norm; p=2 is Euclidean distance
object of class "gensphere.distribution" defined by gensphere
a matrix of (x,y) values in 2-dimensions
an object of class "gensphere.contour" defined by cfunc.new, etc.
optional arguments to the 2-dimensional plot, e.g. col='red', etc.
scale parameter for a normal bump
vector of positive numbers where there are points added around a particular direction
matrices of vertices which are joined together to get a refinement of the grid
a positive number used to scale the contour
These are undocumented functions that are used internally. The functions
gs.cone, gs.elliptical, gs.gen.lp.norm, gs.lp.norm,
gs.proj.normal, gs.vfunc.eval are used in evalutating a contour function.
RefineSphericalTessellation, NearbyPointsOnSphere are used in defining
the tessellation of the contour that identifies bumps and cones.
gs.pdf2d.plot and the plot/print methods are initial attempts at plotting and
printing a summary of objects.
These functions may change or disappear in the future.
